Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mat optimally used for, for example, a tatami floor or a bed.

[0002]

2. Description of the Related Art For example, regarding tatami floors,
From the ones using straw materials, those called chemical tatami mats are becoming mainstream. The tatami floor of the chemical tatami mat is mainly made of a styrofoam board and a cushioning material is laid on the board.

[0003]

When the conventional tatami floor as described above is used, there is no so-called respiratory function of sucking or exhaling humidity. Tatami mats sometimes became sticky. If the tatami mat becomes sticky, it is natural that it is uncomfortable, but moreover, there is a problem that it promotes the occurrence of ticks. Further, even if the board made of polystyrene foam of this chemical tatami is buried in soil, for example, it is not decomposed like wood or iron. Therefore, the polystyrene foam remains in the soil as it is. In order to prevent such a situation, when disposing of the chemical tatami mat, styrene foam is incinerated. However, there is a case where the chemical tatami mat is illegally dumped, and in this case, naturally, only the styrofoam remains. Styrofoam left undisassembled in this way has been one of the environmental problems. A first object of the present invention is to provide a mat having a so-called respiratory function. The second purpose is
It is to provide an eco-friendly mat.

[0004]

According to a first aspect of the present invention, there is provided a mat main body formed by covering the upper and lower portions of an aggregate of wooden slices with a covering material such as burlap and compressing them and sewing them together. A mat auxiliary body is provided below the main body, and the mat main body and the mat auxiliary body are integrated. The second invention provides a mat auxiliary body,
It is characterized in that a carbonized cork board or an insulation board is covered with a covering material such as linen cloth. In the third invention, the mat main body and the mat auxiliary body are overlapped, and a plurality of plate members are interposed between them.
Further, it is characterized in that the mat main body, the plate material, and the mat auxiliary body are stitched together. The fourth invention is characterized in that the upper and lower portions of the aggregate of the wooden slice pieces are covered with a covering material such as linen cloth and compressed, and the lower side thereof is sewn by applying a cardboard.

[0005]

FIG. 1 shows a first embodiment in which the mat of the present invention is used for a tatami floor. The tatami floor has two layers, a tatami floor main body m as a mat main body and a tatami floor auxiliary body s as a mat auxiliary body. The tatami floor main body m collects a large number of wooden slices made of cypress to form an aggregate 1, and covers the upper and lower portions of the aggregate 1 with covering materials 2 and 2 made of linen cloth, and compresses it. At the same time, they are sewn together with hemp yarn 3. The wooden slice pieces are about 20 mm in width and about 80 mm in length.

[0006] The tatami floor auxiliary body s is formed by covering the upper and lower sides of a carbonized cork board 4 to which charcoal powder is attached with covering members 5 and 5 made of linen cloth, and sewing them together with a hemp thread 6. The reason why the boards 4 are covered with the covering members 5 and 5 and sewn together is to prevent the carbonized cork board 4 from being broken and easily collapsed. Further, the carbonized cork board 4 may not have a size corresponding to one tatami mat. In such a case, several carbonized cork boards 4 may be arranged side by side to have a size of one tatami mat, and they may be covered with covering materials 5 and 5 and sewn.

[0007] The tatami floor main body m and the tatami floor auxiliary body s as described above are overlapped with each other.
A sheet material 7 having a width of about 50 mm is interposed between s. The plate member 7 is equal to or slightly shorter than the longitudinal length of the tatami floor main body m and has a width of about 50 mm.
Are arranged at intervals in the width direction. The reason why the plate member 7 is interposed as described above is to provide a so-called waist strength as a tatami floor. The tatami floor main body m and the carbonized cork board 4 that have been sufficiently compressed as described above can provide a considerable strength of the waist. However, even in this case, it may easily bend in the longitudinal direction, and the strength in that direction may be small but insufficient. In such a case, the above-mentioned plate member 7 is interposed to compensate for the shortage.

Then, with the plate member 7 interposed,
The tatami floor main body m and the tatami floor auxiliary body s are sewn with hemp to complete the tatami floor. By covering the tatami floor completed in this way with a tatami mat 8 made of a rush or the like, a tatami mat for one tatami mat is completed. In addition, the said board material 7 does not need to maintain the strength of the waist as a tatami floor. In addition, when the carbonized cork board 4 and the tatami floor main body m are overlapped as described above, since the surface of the carbonized cork board on which these are combined does not collapse, the covering material 5 on the upper side of the carbonized cork board 4 is It is not necessary.

The tatami mat completed as described above has excellent thermal insulation since the main tatami floor m is made mainly of wooden slices of cypress, so that cold under the floor can be completely eliminated. Can shut out. Moreover, due to the action of the cypress, the tatami mats sufficiently absorb moisture, and also exhibit a so-called respiratory function that appropriately exhales them, so that the tatami mats are adapted to climatic conditions in Japan. Because of the respiratory function, the surface of the tatami mat 8 does not become sticky even in humid climatic conditions. Therefore, occurrence of ticks and the like can be prevented.

Further, since the carbonized cork board 4 is used as the tatami floor auxiliary member s, the unit price of the tatami floor can be reduced.
For example, it is conceivable that the main material of the tatami floor auxiliary body s is a wooden sliced piece as in the case of the tatami floor main body m. However, if wooden sliced pieces are used for both the bodies m and s, the cost is inevitably high. Will be. However, if a carbonized cork board is used as in this embodiment, the cost can be reduced as described above. Since the carbonized cork board 4 naturally contains charcoal powder, not only the far-infrared effect, which is a characteristic of charcoal, but also the effect of generating negative ions and absorbing moisture can be expected. Furthermore, in such a tatami mat, a tatami floor main body m is composed of a wooden sliced piece, and a tatami floor auxiliary body s is composed of a carbonized cork board 4, so that a chemical product such as styrene foam is not used. Therefore, it is environmentally friendly.

However, if the effect of charcoal is not expected, no carbonized cork board 4 may be used. Alternatives to the carbonized cork board 4 include, for example, an insulation board and a wooden board having a certain degree of cushioning. These boards are environmentally friendly because they are made of a material that decomposes in nature. Even when a styrofoam board s is conventionally used as the tatami floor assisting body s, the tatami floor main body m is mainly made of a wooden sliced piece, so that the effects such as the hygroscopicity are not impaired. Further, since the tatami floor main body m and the tatami floor auxiliary body s are sewn together with a hemp thread, there is no fear that the tatami floor main body m and the tatami floor auxiliary body s are adversely affected, unlike the case where they are stuck together with an adhesive or the like.
Although the tatami floor is described as an example in the first embodiment, the use of the mat of the present invention is not limited to the tatami floor, and it is natural that the mat can be used for a bed mat, for example.

In the second embodiment shown in FIG. 2, the mat of the present invention is used as a tatami floor M for laying. Since the tatami mats are used by being laid on a hard board such as a flooring, a certain degree of strength is given to the tatami mats by the flooring. Therefore, the strength of the tatami mat floor is not so required. Hereinafter, the tatami floor for the tatami mat will be described, but the same components as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted.

As shown in FIG. 2, an assembly 1 of wooden slices is covered with covering materials 2 and 2 made of linen cloth and compressed. Then, the cardboard 9 is applied to the lower side thereof, and these are sewn together with the hemp thread 3 to complete the tatami floor M. The tatami floor M completed in this way is covered with a tatami table 8 made of a rush or the like, thereby completing a tatami mat for one tatami mat. The cardboard 9 has lower strength and lower stiffness than the carbonized cork board 4 of the first embodiment. However, as described above, the tatami floor for the tatami mat can obtain a certain strength from the flooring side, so that even if the cardboard 9 is used for the tatami floor M, the strength is sufficient. The cardboard 9 also provides a certain degree of stiffness. Therefore, there is no problem even if it is used as a tatami mat floor.

Furthermore, since the cardboard 9 hardly shrinks, the shrinkage of the aggregate 1 of the wooden slice pieces is prevented, and the shrinkage of the tatami floor M is prevented. The cardboard 9 also has a function of absorbing and releasing moisture to some extent, similarly to the aggregate 1 of the wooden slice pieces. Therefore, the tatami floor M using the cardboard 9 is most suitable for laying.

According to the second embodiment, the cardboard 9 through which the needle passes more easily than a wooden board or the like is used. Therefore, in a state where the cardboard 9 is applied to the lower side of the aggregate 1 of the wooden slice pieces compressed and covered with the covering members 2 and 2, these can be sewn together at a time and integrated.
That is, only one stitching operation is required to manufacture the tatami floor M. If only one stitching operation is required, the number of working steps can be reduced, and the manufacturing cost can be reduced.
The cardboard 9 is made of a material that can be decomposed in the natural world, so it is environmentally friendly.
Since there is no need to worry about adverse effects on people.

In consideration of the comfort of the tatami mat and the hygroscopicity and moisture release, the aggregate 1 of the wooden slice pieces is thicker than the cardboard 9.
Therefore, in the second embodiment, the cardboard 9 is provided on the lower side, and the aggregate 1 of the wooden slice pieces is on the tatami table 8 side. This makes it possible to sufficiently exhibit hygroscopicity and moisture release without impairing the touch feeling. However, the cardboard 9 may be provided on the front side only for the purpose of preventing the shrinkage of the aggregate 1 of the wooden slice pieces. Further, in the second embodiment, the tatami floor M for laying mats has been described as an example. However, the use of the mat of the present invention is not limited to this, and it is naturally possible to use the mat as a bed mat. It is. In particular, it is most suitable if it is laid on a plate or the like having a certain strength and used in a place where the reinforcing effect can be obtained from the plate or the like.

[0017]

According to the first aspect of the present invention, since the mat is mainly made of wooden sliced pieces, it is excellent in hygroscopicity and can exhibit a so-called respiratory function. Therefore, for example, when used for a tatami floor, the surface of the tatami mat does not become sticky even when the humidity is high. Also, the occurrence of ticks can be prevented. According to the second aspect, the mat is environmentally friendly.

According to the third aspect of the present invention, since the plate is interposed between the mat main body and the mat auxiliary body, a very stiff mat can be obtained. In particular, it has an effect of not bending in the longitudinal direction. According to the fourth aspect of the present invention, the cardboard, which is easy to pass through the needle as compared with a wooden board or the like, is used. Therefore, the aggregate of the wooden slices compressed and covered with the covering material and the cardboard are sewn at once. Can be integrated. Therefore, only one stitching operation process is required, and the manufacturing cost can be reduced.
